removed rusty and blackened clinkers from the middle part of the machine. Another steely tentacle directed the powder from the basin along a ribbed channel towards some receiver that was hidden from me by the mound of bluish dust. From this unseen receiver a little thread of green smoke rose vertically into the quiet air. As I looked, the handling-machine, with a faint and musical clinking, extended, telescopic fashion, a tentacle that had been a moment before a mere blunt projection, until its end was hidden behind the mound of clay. In another second it had lifted a bar of white aluminium into sight, untarnished as yet, and shining dazzlingly, and deposited it in a growing stack of bars that stood at the side of the pit. Between sunset and starlight this dexterous machine must have made more than a hundred such bars out of the crude clay, and the mound of bluish dust rose steadily until it topped the side of the pit.
The contrast between the swift and complex movements of these contrivances and the inert panting clumsiness of their masters was acute, and for days I had to tell myself repeatedly that these latter were indeed the living of the two things.
The curate had possession of the slit when the first men were brought to the pit. I was sitting below, huddled up, listening with all my ears. He made a sudden movement backward, and I, fearful that we were observed, crouched in a spasm of terror. He came sliding down the rubbish and crept beside me in the darkness, inarticulate, gesticulating, and for a moment I shared his panic.

At first I could see no reason for his frantic behaviour. The twilight had now come, the stars were little and faint, but the pit was illuminated by the flickering green fire that came from the aluminium-making. The whole picture was a flickering scheme of green gleams and shifting rusty black shadows, strangely trying to the eyes. Over and through it all went the bats,
